>Release: DragonFly 3.1
Clang apparently doesn't bootstrap itself, but builds with the system compiler.
The DragonFly compilers will automatically insert an rpath of "/usr/lib/gcc41" or "/usr/lib/gcc44" to every built executable. And it's doing it for clang.
> readelf -a /usr/pkg/bin/clang++ | grep -i rpath
0x000000000000000f (RPATH) Library rpath: [/usr/lib/gcc44:/usr/pkg/lib]
> ldd /usr/pkg/bin/clang++
libpthread.so.0 => /usr/lib/libpthread.so.0 (0x802359000)
libstdc++.so.9 => /usr/lib/gcc44/libstdc++.so.9 (0x802570000)
libm.so.3 => /usr/lib/libm.so.3 (0x802884000)
libc.so.7 => /usr/lib/libc.so.7 (0x802aa3000)
The result is that clang tries to use system gcc libstd++ which doesn't end well.
Build clang on any compiler that automatically inserts a base runpath. Perhaps DragonFly is unique here.
Clang needs to build itself, and it needs to specify it's own libstd++ inside the build directory rather than relying on system libstdc++.

This PR can be closed.
1) The original report was in error, this was caused by something else
2) It's been resolved in recent clang packages and recently upstream as
